How this service works
NINDS 1995 IV alteplase milligram arithmetic from weight: total_mg = min(0.9 × weight_kg, 90), 10% bolus, 90% infusion over 60 minutes. Reports milligrams and whether the 90 mg cap applied. Not a medical device, not a prescription, not an eligibility screen, and not tenecteplase.
Output
Returns the total alteplase dose in milligrams (0.9 × weight_kg, capped at 90 mg), the 10% bolus dose in mg, the 90% infusion dose in mg to be given over 60 minutes, and a boolean or flag indicating whether the 90 mg maximum cap was applied.
Example use cases
Stroke team dose verification at bedside
“Our patient just came in with acute ischemic stroke and weighs 68 kg — calculate their alteplase dose using the NINDS 1995 protocol and tell me the bolus and infusion amounts.”
Heavy patient cap check
“Patient weighs 110 kg. What's the alteplase dose under the NINDS 1995 protocol? Does the 90 mg cap apply, and what's the split between bolus and infusion?”
Lightweight patient dosing
“Calculate the IV alteplase stroke dose for a 52 kg patient using NINDS 1995 — show me the total milligrams, 10% bolus, and 90% infusion over 60 minutes.”

Endpoint
GEThttps://api.magentlab.com/api/calc/alteplase_strokeWhen to prefer
Use this endpoint when you need fast, reliable arithmetic for the NINDS 1995 IV alteplase dosing protocol in acute ischemic stroke — specifically the 0.9 mg/kg formula capped at 90 mg with the 10%/90% bolus/infusion split. This is NOT for tenecteplase, NOT an eligibility screen, and NOT a medical device — it is purely a dosing arithmetic calculator. Prefer this over manual calculation to avoid arithmetic errors in high-stakes clinical workflow automation.
Side effects
- Missing weight_kg parameter returns a validation error
- weight_kg outside plausible range (e.g. 0, negative, or extremely high values) may return an error or clamped result
- Non-numeric weight_kg causes a schema validation failure
- Service unavailable or payment not processed returns HTTP 402 or 5xx
